* libavfilter: Remove DNNReturnType from DNN ModuleShubhanshu Saxena2022-03-12
| | | | | | | | | | This patch removes all occurences of DNNReturnType from the DNN module. This commit replaces DNN_SUCCESS by 0 (essentially the same), so the functions with DNNReturnType now return 0 in case of success, the negative values otherwise.

* configure: move ranlib -D test after setting defaultsAdrian Ratiu2022-03-11
| | | | | | | | | | | | | | | | | In Gentoo and ChromeOS we want to allow pure LLVM builds without using GNU tools, so we block any unwanted mixed GNU/LLVM usages (GNU tools are still kept around in our chroots for projects like glibc which cannot yet be built otherwise). The default ${cross_prefix}${ranlib_default} points to GNU and fails, so move the test a bit later - after the defaults are set and the proper values get overriden - such that ffmpeg configure calls the llvm-ranlib we desire.

* avformat: add DFPWM WAV container supportJack Bruienne2022-03-10
| | | | | | | | | | | | | | | | | | | This commit adds support for storing DFPWM audio in a WAV container. It uses the WAVEFORMATEXTENSIBLE structure, following these conventions: https://gist.github.com/MCJack123/90c24b64c8e626c7f130b57e9800962c The implementation is very simple: it just adds the GUID to the list of WAV GUIDs, and modifies the WAV muxer to always use WAVEFORMATEXTENSIBLE format with that GUID. This creates a standard container format for DFPWM besides raw data. It will allow users to transfer DFPWM audio in a standard container format, with the sample rate and channel count contained in the file as opposed to being an external parameter as in the raw format. This format is already supported in my AUKit library, which is the CC analog to libav (albeit much smaller). Support in other applications is TBD.

* avformat: add DFPWM raw formatJack Bruienne2022-03-10
| | | | | | | | | | | | | This patch builds on my previous DFPWM codec patch, adding a raw audio format to be able to read/write the raw files that are most commonly used (as no other container format supports it yet). The muxers are mostly copied from the PCM demuxer and the raw muxers, as DFPWM is typically stored as raw data. Please see the previous patch for more information on DFPWM.

* avcodec: add DFPWM1a codecJack Bruienne2022-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the wiki page (https://wiki.vexatos.com/dfpwm): > DFPWM (Dynamic Filter Pulse Width Modulation) is an audio codec > created by Ben “GreaseMonkey” Russell in 2012, originally to be used > as a voice codec for asiekierka's pixmess, a C remake of 64pixels. > It is a 1-bit-per-sample codec which uses a dynamic-strength one-pole > low-pass filter as a predictor. Due to the fact that a raw DPFWM decoding > creates a high-pitched whine, it is often followed by some post-processing > filters to make the stream more listenable. It has recently gained popularity through the ComputerCraft mod for Minecraft, which added support for audio through this codec, as well as the Computronics expansion which preceeded the official support. These both implement the slightly adjusted 1a version of the codec, which is the version I have chosen for this patch. This patch adds a new codec (with encoding and decoding) for DFPWM1a. The codec sources are pretty simple: they use the reference codec with a basic wrapper to connect it to the FFmpeg AVCodec system. To clarify, the codec does not have a specific sample rate - it is provided by the container (or user), which is typically 48000, but has also been known to be 32768. The codec does not specify channel info either, and it's pretty much always used with one mono channel. However, since it appears that libavcodec expects both sample rate and channel count to be handled by either the codec or container, I have made the decision to allow multiple channels interleaved, which as far as I know has never been used, but it works fine here nevertheless. The accompanying raw format has a channels option to set this. (I expect most users of this will not use multiple channels, but it remains an option just in case.) This patch will be highly useful to ComputerCraft developers who are working with audio, as it is the standard format for audio, and there are few user-friendly encoders out there, and even fewer decoders. It will streamline the process for importing and listening to audio, replacing the need to write code or use tools that require very specific input formats. You may use the CraftOS-PC program (https://www.craftos-pc.cc) to test out DFPWM playback. To use it, run the program and type this command: "attach left speaker" Then run "speaker play <file.dfpwm>" for each file. The app runs in a sandbox, so files have to be transferred in first; the easiest way to do this is to simply drag the file on the window. (Or copy files to the folder at https://www.craftos-pc.cc/docs/saves.) Sample DFPWM files can be generated with an online tool at https://music.madefor.cc. This is the current best way to encode DFPWM files. Simply drag an audio file onto the page, and it will encode it, giving a download link on the page. I've made sure to update all of the docs as per Developer§7, and I've tested it as per section 8. Test files encoded to DFPWM play correctly in ComputerCraft, and other files that work in CC are correctly decoded. I have also verified that corrupt files do not crash the decoder - this should theoretically not be an issue as the result size is constant with respect to the input size.

* libavfilter: vf_scale: Properly take in->color_range into accountMartin Storsjö2022-03-07
| | | | | | | | | | | | | | | | | | | | | While swscale can be reconfigured with sws_setColorspaceDetails, the in/out ranges also need to be set before calling sws_init_context, otherwise the initialization might choose fastpaths that don't take the ranges into account. Therefore, look at in->color_range too, when deciding on whether the scaler needs to be reconfigured. Add a new member variable for keeping track of this, for being able to differentiate between whether the scale filter parameter "in_range" has been set (which should override whatever the input frame has set) or whether it has been configured based on the latest frame (which should trigger reconfiguring the scaler if the input frame ranges change).
